She told ESPN she is fully committed to wrestling and won't just be making cameos at the WWE's biggest events. "This is my life now. Yeah, they have first priority on my time for the next several years," Rousey said. "This is not a smash and grab, this is not a publicity stunt."

A full area of roaring fans welcomed Rousey as she took to the stage and pointed to a WrestleMania sign taking place in New Orleans on April 3. Joan Jett's Bad Reputation played with flashing lights and fog machines as Rousey began setting up the story line for her appearance in Wrestlemania 34 later this year.

UFC fans tweeted their support for Rousey's transition to WWE. She told WWE.com, "This has been a dream of mine since me and all my girlfriends would sit around and watch wrestling together. No matter how much I tried to do other things in my life, this kept following me around. It’s time to take a hint from the universe and go for it."

Rousey announced she would stop fighting after going undefeated until losing two fights in a row, one was a 48-second loss to Amanda Nunes in UFC 207 in December of 2016. Rousey got her nickname "Rowdy" from WWE Hall of Famer "Rowdy" Roddy Piper who died in 2015.
